    Microsoft Surface Pro (5th gen) model 1796 - no power
    by PantherDave
    Hi all!

    I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

    I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

    Asus Probook P5440UF-XB74 power issue
    by GLISIT
    Hi all,

    TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


    I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

    A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

    Samsung UE75MU7009TXZG Endless Power Cycle

    Samsung UE75MU7009TXZG Endless Power Cycle

    Hi everyone and thanks in advance for any help I might get here

    My Samsung TV is about 4 years old. The exact model number is UE75MU7009TXZG.
    About half a year ago I started seeing occasional green frames pop up while watching movies. I mean literally green frames. Not the image turning green, but the entire screen turning green for a split second. This happened maybe once or twice during a 2 hour movie. So no big deal, but clearly something was not quite right.

    Since a few days, the TV won't turn...

    Samsung TV won't turn on ... keeps cycling the power relay on & off
    by Journey11
    Hi All,
    First time posting here ... my name is Kevin but my friends call me Journey.
    I have a Samsung 75" LCD model UN75RU8000FXZA that I don't remember the original fault other than it wouldn't power up anymore.
    After it sat for many month's I decide to look at it again. The motherboard seemed to have power regulation issues. After much fussing I decided to just get a new MB.
    It came a few days ago and I installed it now just cycles the power relay on and off ... when on the backlights light up and then dim and then relay kicks off and the whole things starts again....

    Samsung SyncMaster 215TW buzzing / lightning in power board socket
    by nh2
    This is my first post here. I just fixed my first 2 broken displays by replacing broken capacitors (Samsung SyncMaster 226BW, and Samsung SyncMaster 213T). But I have a third one I'm unable to fix, and am eager to fix as well:

    My Samsung SyncMaster 215TW makes a buzzing / hissing sound when turned on.

    The sound is louder the brighter the monitor is, e.g. in the "Game" preset is is even louder than in a softer preset.

    Opening up the monitor and unplugging the small socket cables that run from the power board to the LCD, I can see a small blue...
